British MPs have just approved the use of Syria airstrikes against ISIS. 397 Members of Parliament voted in favour of airstrikes, with 223 opposed. The debate in the House of Commons lasted more than ten hours, with some MPs reportedly close to tears by the end of it.

This week MPs will vote over whether to take military action against the so-called Islamic State (ISIS) in Syria. David Cameron says voting against military action makes you a terrorist sympathiser. What’s going on in Syria and should we get involved?
